2016-02-23clk: ti: omap3+: dpll: use non-locking version of clk_get_rateTero Kristo1-1/+2
As the code in this file is being executed within irq context in some cases, we must avoid the clk_get_rate which uses mutex internally. Switch the code to use clk_hw_get_rate instead which is non-locking. This fixes an issue where PM runtime will hang the system if enabled with a serial console before a suspend-resume cycle.

2015-11-30clk: ti: omap5+: dpll: implement errata i810Tero Kristo1-1/+24
Errata i810 states that DPLL controller can get stuck while transitioning to a power saving state, while its M/N ratio is being re-programmed. As a workaround, before re-programming the M/N ratio, SW has to ensure the DPLL cannot start an idle state transition. SW can disable DPLL idling by setting the DPLL AUTO_DPLL_MODE=0 or keeping a clock request active by setting a dependent clock domain in SW_WKUP. This errata impacts OMAP5 and DRA7 chips, so enable the errata for these. Signed-off-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

2015-10-02clk: ti: dflt: fix enable_reg validity checkSuman Anna1-2/+2
The default clock enabling functions for TI clocks - omap2_dflt_clk_enable() and omap2_dflt_clk_disable() perform a NULL check for the enable_reg field of the clk_hw_omap structure. This enable_reg field however is merely a combination of the index of the master IP module, and the offset from the master IP module's base address. A value of 0 is perfectly valid, and the current error checking will fail in these cases. The issue was found when trying to enable the iva2_ck clock on OMAP3 platforms. So, switch the check to use IS_ERR. This correction is similar to the logic used in commit c807dbedb5e5 ("clk: ti: fix ti_clk_get_reg_addr error handling").

2015-06-04CLK: TI: always enable DESHDCP clockTomi Valkeinen1-1/+6
DESHDCP clock is needed on DRA7 based SoCs to enable the DSS IP. That clock is an odd one, as it is not supposed to be any kind of core clock for DSS, and we don't even support HDCP, but the clock is still needed even for the HWMOD framework to be able to reset the DSS IP. As there's no support for multiple core clocks in the HWMOD framework, we don't have any obvious place to enable this clock when DSS IP is being enabled. Furthermore, the HDMI on OMAP5 DSS is the same as on DRA7, and OMAP5 does not have any such clock configuration bit. This suggests that on OMAP5 the DESHDCP clock is always enabled, and for DRA7 we have the possibility to gate it. So, as we don't have any clean way to enable and disable the clock based on the need, this patch enables the clock at boot time, making it work similarly to OMAP5.

With the legacy clock data gone, this is no longer needed under platform, so move it under the clock driver itself. Remove the exported clock driver APIs as well, as these are not needed outside clock driver anymore. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02clk: ti: omap2430: move clock support code under clock driverTero Kristo2-0/+36
With the legacy clock support gone, this is no longer needed under platform code-base. Thus, move this under the TI clock driver, and remove the exported API from the public header. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02clk: ti: dflt: move support for default gate clock to clock driverTero Kristo3-1/+322
With the legacy support gone, OMAP2+ default gate clock can be moved under clock driver. Create a new file for the purpose, and clean-up the header exports a bit as some clock APIs are no longer needed outside clock driver itself. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02clk: ti: dpll: move omap3 DPLL functionality to clock driverTero Kristo4-6/+891
With the legacy clock support gone, OMAP3 generic DPLL code can now be moved over to the clock driver also. A few un-unused clkoutx2 functions are also removed at the same time. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02clk: ti: move omap2_clk_enable_init_clocks under clock driverTero Kristo6-0/+32
This is no longer used outside clock driver, so move it under the driver and remove the export for it from the global header file. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02clk: ti: autoidle: move generic autoidle handling code to clock driverTero Kristo3-8/+116
This is no longer needed in platform directory, as the legacy clock data is gone, so move it under TI clock driver. Some static functions are renamed also. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02clk: ti: move interface clock implementation under drivers/clkTero Kristo3-1/+69
With the legacy clock support gone, the OMAP interface clock implementation can be moved under the clock driver. Some temporary header file tweaks are also needed to make this change work properly. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02clk: ti: move OMAP4+ DPLL implementation under drivers/clkTero Kristo3-3/+250
With the legacy clock support gone, the OMAP4 specific DPLL implementations can be moved under the clock driver. Change some of the function prototypes to be static at the same time, and remove some exports from the global TI clock driver header. Signed-off-by: Tero Kristo <t-kristo@ti.com>
2015-06-02clk: ti: move generic OMAP DPLL implementation under drivers/clkTero Kristo3-1/+373
With the legacy clock data now gone, we can start moving OMAP clock type implementations under clock driver. Start this with moving the generic OMAP DPLL clock type under TI clock driver. Signed-off-by: Tero Kristo <t-kristo@ti.com>
